In https://docs.atlas.mongodb.com/configure-api-access/#provide-access-to-whitelisted-api-operations it says:

On the resources pages in this guide, whitelisted operations are marked as such.

To me this means that when I look at the 'resources page' (== the API endpoints "Reference" subsection) it will show me that some need whitelisting and that some don't. But that info isn't there.

As best as I could find out all the API operations (maybe with the exception of the one that retrieves the Root resource) in Atlas require that the source IP address of the API client be whitelisted.

If so, then could "On the resources pages in this guide, whitelisted operations are marked as such." please be replaced with "All the API endpoints used in Atlas require API clients to be whitelisted" or something like that.

But if it's truly variable (i.e. some API endpoints will respond to client requests without consideration of their source IP address) then could the documentation please reflect which do and which don't.
